List dictionary..(sort)?

Question

Hi.
please how can we use sort or any other method to have a result like that.
[(3,"b"),(5,"a"),(66,"k")]
==>
[(5,"a"),(3,"b"),(66,"k")]
(trier les 2emes valeurs et non les premières.. et aussi comment les options de la méthode change si on veut mettre en ordre les numéros ou bien les lettres. )
Thank you.
